Incorporate state name into key for Redis grain storage

[ReubenBond]

Fixes #8485

This PR incorporates the state name into the key format for the Redis grain storage provider.
To continue using the key format from the beta versions of storage provider, you will need to configure the delegate used to resolve a key via the RedisStorageOptions.GetKey property. A helper method is provided to do so as an extension method on OptionsBuilder<RedisStorageOptions>. Here is an example:

siloBuilder
    .AddRedisGrainStorage("MyGrainStorage", (OptionsBuilder<RedisStorageOptions> optionsBuilder) =>
    {
        optionsBuilder.UseGetRedisKeyIgnoringGrainType();
        optionsBuilder.Configure(options =>
        {
            options.ConfigurationOptions = ConfigurationOptions.Parse(connectionString);
        });
    })
